Device for measuring load leakage or aging by using piezoelectric igniter

Abstract

The invention relates to a device for measuring load leakage or aging by using a piezoelectric igniter. The device comprises a piezoelectric igniter, a load, a probe, a display, a standard resistanceinput module, a single chip microcomputer, and an amplifier; the piezoelectric igniter is connected with the load; one end of the load contacts the probe, and the other end of the load is grounded; the probe contacts the load; the probe is connected to the amplifier; and the amplifier, the probe, the display, and the standard resistance input module are connected to the single chip microcomputer.The piezoelectric igniter discharges a pulse current of 12V to its load, the load is grounded, the probe contacts the load; the principle of charging by induction is used, the current generated by theprobe through the induction is amplified by the amplifier and then flows through the single chip microcomputer, and the single chip microcomputer calculates and analyzes voltage and current information to obtain the resistance value of the load, and the resistance value and the standard resistance value input by the standard resistance input module are compared, and in this way, the leakage or aging of the load is measured and displayed on the display screen. The device is simple and effective, and is accurate in measurement.

Description

technical field [0001] The invention relates to a device for measuring load leakage or aging by using a piezoelectric igniter, which belongs to the technical field of measuring equipment. Background technique [0002] At present, with the changes of the times and the development of society, the number of electrical appliances has also increased, which has brought convenience to people's lives to a large extent. Inevitably, the frequency of people's electricity use also increases with the increase in the number of electrical appliances. In today's society, due to rising prices or other reasons, people will continue to use certain electrical appliances or some parts of electrical appliances that need to be replaced at regular intervals for a long time with the concept of "saving". If electrical appliances do not pay attention to maintenance, they will be prone to aging, which will lead to leakage problems. If people cannot find such problems in time when using electrical appl...

In today's society, due to rising prices or other reasons, people will continue to use certain electrical appliances or some parts of electrical appliances that need to be replaced at regular intervals for a long time with the concept of "saving". If electrical appliances do not pay attention to maintenance, they will be prone to aging, which will lead to leakage problems. If people cannot find such problems in time when using electrical appliances, safety accidents will easily occur, which will not only endanger the personal safety of the people, but also cause harm to the people.
